Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Robust estimation of key leaf traits from reflectance spectroscopy of herbarium specimens

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Community‐wide efforts to digitize herbarium specimens have facilitated novel uses of specimen data across scales. However, the need for destructive sampling has prevented large‐scale examination of foliar functional traits. We demonstrate that nondestructive reflectance spectra are an effective tool for estimating leaf traits from herbarium ...

Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro‐CT Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.

The Fiery Eyes of a Maenad: Origin Determination of Faceted Garnet Eye Inlays in a Roman Bronze Bust From Southern Tyrol

open access: yesArchaeometry, EarlyView.
ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Between Gaps and Voids: An Archaeometrical Study of Degraded Fibers in a Sherd From the Cueva dos Chinches Muertas, Siltzul (Raxruha, Alta Verapaz, Guatemala)

open access: yesArchaeometry, EarlyView.
ABSTRACT In 2019, excavations at the Cueva dos Chinches Muertas carried out by the Raxruha Viejo Project uncovered a small ceramic sherd distinguished by a stratified structure composed of multiple layers of textile imprints, both superficial and transversal.

CANRIG: Cross‐Attention Neural Face Rigging with Variable Local Control

open access: yesComputer Graphics Forum, EarlyView.
Abstract Facial animation is one of the most labor‐intensive aspects of animation and VFX, as traditional rigging consumes weeks of expert time and forces animators to spend countless hours manipulating hundreds of controls to achieve varied expressions.

Decoverslipping of Archival Cytology Aspirate Smears for Ancillary Studies: A Review of Methods and Institutional Experience With Freezer‐Based Techniques

open access: yesCytopathology, EarlyView.
Freezer‐based decoverslipping of archival cytology aspirate smears achieved only 32.5% slide‐level success (26/80), with mounting medium composition and coverslip material, not freezing temperature or duration, identified as dominant determinants, underscoring the need to align coverslipping practices with anticipated ancillary testing requirements ...

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

open access: yesThe FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).
